Well turns out here in the USA we have something similar called a Potato Bug, or sometimes called a Jerusalem Cricket.
What is the caterpillar going to turn into?

The slightly blown out background makes you focus more on the caterpillar, and gives it a slight dreamy effect, plus everything that you wanted in focus is really sharp. The colour is also really vibrant.
